These signals are used with brake control function.
To output the warning signals, assign function
intelligent output terminals [11] and [12], or to the relay output terminal.
Refer to chapter 3 for detailed explanation of the brake control function.

Required settings
Notes:
• The example circuit for terminal [11] drives a relay
coil. Note the use of a diode to prevent the
negative-going turn-off spike generated by the coil
from damaging the inverter's output transistor.
